Definitions

  • the present invention relates to an apparatus for transporting an article transport container including at least two sets of container supporting means for supporting and lifting the article transport container from both sides.
  • Patent Document 1 discloses a container support pin in which a large number of pins are arranged at appropriate intervals in the horizontal and vertical directions so that the intended container support action can be exhibited. Was also described as a tapered pin.
  • the container support pin is made of the above-mentioned tapered taper pin, even if the structure on the container side is slightly different as described above, if the overhanging rib is present, the container support pin is provided below the overhanging rib. It was thought that the pin for the container could be securely inserted. However, in reality, since the container support pin was a tapered taper pin, one overhanging rib or two overhanging upper and lower overhanging ribs were used in a side view. In the case where the upper and lower two container supporting pins are sandwiched from above and below, or when the tips of the upper and lower two container supporting pins enter the inside of the upper and lower two projecting ribs in side view, the container supporting pin is used.
  • the outer diameter of the portion of the pin adjacent to the overhang rib changes greatly as the container supporting pin advances from the state where the small-diameter distal end portion of the pin is adjacent to the side surface of the overhang rib in the direction overlapping the overhang rib. Therefore, the peripheral surfaces of the container support pins begin to press against the side surfaces of the overhang ribs, and the pressing force gradually increases with the advance of the container support pins, and finally, the gap between the container support pins and the overhang ribs increases.
  • the frictional resistance disables the advancement of the container support pin relative to the article transport container, and thereafter the spring that urges the container support pin in the protruding direction is compressed, and the friction between the container support pin and the overhang rib is reduced. The force will increase further.
  • the container supporting means when the container supporting means is horizontally moved away from the container after being conveyed to a predetermined place, the container supporting pins which are in contact with the container-side projecting rib with a large frictional force as described above are extended. In some cases, it is difficult to extract the container horizontally from the container, and the position or orientation of the container may be changed by dragging the container.
  • the present invention proposes an elevating / lowering transport device for an article transport container that can solve the conventional problems as described above, and an elevating / lowering transport device for an article transport container according to the present invention will be described later.
  • the reference numerals used in the description of the embodiment are attached in parentheses, so that they can be freely moved close to and away from the article transport container (1) in the horizontal direction. It is provided with at least two sets of container supporting means (11, 12) which can move up and down, and these container supporting means (11, 12) project horizontally in the side where the container (1) is located, and are movable back and forth.
  • the container (11, 12) has a sword mountain-like structure provided with a number of container support pins (17a, 17b) biased and held at positions protruding from the front member (22), and the container ( Due to the approach movement with respect to 1), the downward stepped surface formed outside the container (1) (the vertical With the container supporting pins (17a, 17b) entered under the lower end surface of the wall portion), the lifting and lowering transport device for an article transport container configured to support the container (1) so as to be liftable,
  • a pin body (18) projecting from a front member (22) of the container support means (11, 12) of the container support pin (17a, 17b) has a flat tip surface (18a) perpendicular to an axis. And is formed in a tapered pin shape having a larger diameter as it approaches the flat tip surface (18a).
  • the container supporting pin can advance and move toward the container at a position adjacent to the projecting rib of the article transport container with the movement of the container supporting means, because the container supporting pin
  • the condition is that the flat end surface of the maximum diameter of the pin main body does not overlap with the overhang rib when viewed from the axial direction of the pin main body. If they overlap, when the container supporting pin moves closer to the article transporting container along with the movement of the container supporting means, the flat tip surface of the maximum diameter of the pin main body of the container supporting pin has an overhanging rib. The container support pin comes into contact with the front surface and no further movement of the container support pin is performed.
  • the tip of the maximum diameter of the pin body becomes the chamfer of the overhanging rib. Even when the pin main body rides on the horizontal side surface of the overhanging rib along the corner, as in the case where the entirety of the pin body is a columnar body having the same outer diameter as the flat distal end surface having the maximum diameter, the container supporting means does not convey the article.
  • the pin body and the overhanging rib are not in sliding contact with each other over the entire length of the overlapping area, and only the tip of the maximum diameter of the pin body is in contact with the horizontal side surface of the overhanging rib. Just touch.
  • the vertical position of the container supporting pin and the projecting rib on the side of the container for transporting the article is the same as when the conventional container supporting pin having a tapered taper pin shape is used. Due to the relationship, there is no situation in which the two sides come into pressure contact with significant frictional force, and even if the two sides come into sliding contact with each other, even if the two sides come into sliding contact with each other, the container support pin side
  • the slide contact point with the overhang rib is only one point around the tip of the maximum diameter of the pin body, and the frictional force between the two at that time is also extremely small.
  • the container support means when the container support means reaches the forward limit to the article transport container side, there is only a container support pin whose flat end surface is pressed against the front surface of the overhanging rib by an urging force, and other container support pins are provided. Reach the advance limit position without substantially pressing against the horizontal side surface of the overhang rib, so that the container support means moves upward through the container support pin located immediately below the overhang rib and the overhang rib. Thus, the article transport container can be supported and lifted by the container support means.
  • the container support pin may be laterally released from the area overlapping with the overhanging rib by extending the container support pin, Unlike the conventional case, there is no container support pin that presses against the horizontal side surface of the overhang rib on the article transport container side with a great frictional force, so that the container support means can be moved to the predetermined position without receiving any special resistance.

  • the interval between the container support pins must be abnormally reduced, in the present invention, since the base is a pin body having a tapered pin shape with a tapered tapered root, the container support pins adjacent to each other vertically on the same column A structurally necessary interval between the roots can be ensured without difficulty.

  • the tips are partially overlapped with each other, so that even if the overhang rib is thin, there is no phenomenon that the overhang rib is forced into the space between the vertically adjacent pin bodies in side view. .
